3M Scotch-Weld Nylon Bonder Structural Adhesive DP8910NS, Black, 45 mL Duo-Pak

There is no plunger mechanism for dispensing the adhesive and 10:1 mixing tips are required. You must buy these separate. The product description should tell us that. Not eligible for return so I have $25 of useless epoxy. I made separate plungers for each side and put 1/8" marks on them. I push out an 1/8" of the 'large' volume first, then switch to the skinny plunger and push out 1/8" of the small volume side. Mix them VERY well in a small disposable dixie cup. I wanted this for gluing a nylon spur gear to a brass rod. The adhesive did not adhere great to either one.

3M scores a win. DP8910 (NS Black) was recommended by a respected colleague for bonding to nylon. So I tested it. Some surface prep of both surfaces to be bonded is required, basically sanding and wipe clean with IPA alcohol. The factory directions are clear and thorough. BE SURE you get the correct mixing tubes (10:1) when ordering from Amazon. Lightly load the bond joint during cure. Once set, these bonded joints are here to stay, topside or submerged. Thumbs up performance.

Trying to bond nylon plug into a carbon tube. The 3M tech said this product would do the job. No luck. Plug twists right out after 48 hours... No one seems to be able to make an adhesive that works for this material!
